How do you test the fuel pump on a Ford Probe?

To test the fuel pump on a Ford Probe, first ensure the ignition is off and disconnect the negative battery terminal. Then, locate the fuel pump relay and check for proper operation by swapping it with a similar relay from another system. After that, use a fuel pressure gauge to connect to the fuel rail's test port, turn the ignition to the "on" position (without starting the engine), and check the pressure reading against the manufacturer's specifications. If the pressure is low, the fuel pump may need to be replaced.
